Clinical Information
  • A blockage of electrical conduction within the sinoatrial node resulting in the failure of impulse transmission from the sinoatrial node.
  • A blockage of electrical conduction within the sinoatrial node resulting in the failure of impulse transmission from the sinoatrial node. (nci)
  • A blockage of electrical conduction within the sinoatrial node resulting in the prolongation or failure (intermittent or complete) of impulse transmission from the sinoatrial node to the surrounding atrial tissue.

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 426.6 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
